COP3 Lighting Techniques Exercise: Observation 2

Context of Practice 3 Lighting Techniques Exercise: Observation 2
The questions below are taken from the book Light for Visual Artists, and will be what I am going to focus my answers around:
Observe the light. What is its main source? Are there any other light sources? What colour is it? Is it direct light from a bulb or the sun, or is it diffuse light from the sky or a window? Are there any shadows? Do you have a hard edge? Are there any atmospheric factors affecting the light, such as mist, dust, or haze? Is the light pleasing to the eye? If yes, why?

Photograph 2 - (Jokulsarlon Glacier Sunset) by Eric Hines
Observe the light. What is its main source?
The sun.
Are there any other light sources?
No.
What colour is it?
The sunlight coming down is as the sun is nearly setting so it creates lots of orange and yellow light from it, with the occasional light pink tones mixed in. This then works against the blue of the sky at the opposite side of the shot and this makes a really lovely contrast as the sky is so blue and clear in between the clouds.
Is it direct light from a bulb or the sun, or is it diffuse light from the sky or a window?
The light is diffuse light coming from the sun but there is also a spot light element mixed in as well with the reflection of the sun on the water. 
Are there any shadows?
There are some really lovely shadows in this scene, and especially on the rocks that are on the edge of the water. These shadows are very dark as there really isn't a lot of light getting to them, this shadow is also then reflected in the water which creates a really nice effect and look to the shot. There are also some shadows on the clouds that make a really nice effect, you also get the sun light coming through as well, bringing out the shape of the clouds at the same time, which makes them feel fluffy and gives them more shape. 
Do you have a hard edge?
On the clouds there isn't a hard edge, but on the rocks, there is. As the rocks are facing completely away from the sunlight there are faces that are completely in shadows. 
Are there any atmospheric factors affecting the light, such as mist, dust, or haze?
Again there isn't a lot of atmospheric factors but there is a small amount of haze coming from the sun, you also get a really nice reflection on the water as well. 
Is the light pleasing to the eye? If yes, why?
This photograph is beautiful, and the colours really do stand out against the blandness of the environment. The cold landscape is really brought alive with that pop of colour from the sun and its reflection, but the blueness of sky provides a really nice contrast as well, and makes the atmosphere feel colder, as the blue of the sky is reflected not only onto the water but also onto the rocks and I believe there is snow as well that is blue due to the sky.
